Nikon d7000 cutting coefficient

What is the cutting factor of Nikon D7000 camera? 1.5-2.0 times.

For an entry-level digital SLR, this coefficient is1.5-2.0x. For example, a 28mm lens has a moderate wide-angle viewing angle on a full-frame camera, but on a camera with a cropping factor of 1.6X, the viewing angle of an image produced by the same lens is the same as that produced by a 45mm lens on a full-frame camera (28x1.6 Narrowing the viewing angle is a disadvantage when you want to get a wide angle _ Super wide angle becomes wide angle, and wide angle becomes "normal". However, when you want to get a narrow perspective, the cutting factor once again becomes an advantage. When a photographer shoots a distant object with a telephoto lens, cropping makes it easier for the target to fill the picture. The viewing angle of a 300mm lens on a camera with a cropping factor of 1.6X can only be obtained by installing a 480mm lens on a full-frame camera.

Most digital slrs (especially entry-level ones) on the market use the nominal APS-C sensor, which is smaller than the standard 24x36mm(35mm) film frame. For example, the sensor size used by many consumer digital SLR cameras is 15x23mm. In this way, the image data collected by the sensor is smaller than the frame area of 35mm, which is equivalent to cutting off the corners of the Quan Huafu of 24x36mm film. Due to the above cutting, the effective viewing angle decreases proportionally from the smaller sensor size to the Quan Huafu (reference system).
